Overview
The LS173 is a Portable multi-function Handheld color difference meter with a 3.5-inch IPS color capacitive Touchscreen for good operation experience. The instrument has multiple built-in color cards, which can quickly match the measurement Color to the closest Color Chart number, and has the color difference contrast function. It supports a variety of standard color addition methods, can set the color difference threshold and flexibly select the Color difference formula to achieve rapid QC detection.

Principle
The LS173 uses a D/8 light path structure, including specular reflection (SCI), using a full-light spectrum LED Illuminant, with a Wavelength range of 400-700nm and a interval of 10nm. Color measurement is performed based on standard illuminator D65 and 10 ° field of view conditions, and various Color spaces and Color difference formulas are calculated through built-in algorithms to achieve Color matching and color difference contrast.
Applications
Color measurement, color difference comparison, QC detection, Color matching
